errorhandling.js

// Lovely simple-to-read code:

function handleDelete(request, response) {
  getBlogByGuid(request.url.query.guid, function gotBlog(err, blog) {
    deleteDocumentById(blog.id, function deletedBlog(err, status) {
      // Deleted OK
      response.writeHead(200);
      response.end('Blog Deleted');
    })
  });
}

// Now with some error checking:



function handleDelete(request, response) {
  function reportError(msg, err) {
    console.log('Blogs', msg);
    response.json(500, JSON.stringify(err));
  }
  
  if(! "guid" in request.url.query))
    reportError('Error - Missing guid in handleDelete', err) && return;

  getBlogByGuid(request.url.query.guid, function gotBlog(err, blog) {
    if(err == true)
      reportError('Error in getBlogByGuid callback in handleDelete', err) && return;

    deleteDocumentById(blog.id, function deletedBlog(err, status) {
      if(err == true)
        reportError('Error in deleteDocumentById callback in handleDelete', err) && return;

      // Deleted OK
      response.writeHead(200);
      response.end('Blog Deleted');
    })
  });
}

// :( What happened to my lovely readable code?
